This late 19th or early 20th c. jasperware button measures 1 & 1/4 by 3/4 inches (NBS medium) and is it excellent condition. I am satisfied the jasperware is Wedgwood, as this lady appears in at least books on Wedgwood, but since it is bezel-set in brass, we cannot divine the mark. Inasmuch as the plaque is modern, whether it is any other jasperware but Wedgwood has little impact on its value. This one is just a pretty button. :)
